Protein A chromatography is widely used as the affinity capture step of both mAbs and Fc-fusion proteins because of its high degree of selectivity. Variations in elution behaviour of the protein A capture step require more process development work and could have an impact on t...
injections of cleaning solution at a volume equal to the column bed volume, followed by 2 or 3 injections of equilibration buffer—for example, 2 x 100 μL cleaning solution, POROS ® Chromatography Media Group, Applied Biosystems, Bedford, MA ...

26.3.6.3 Performing a Protein A Separation using Liquid Chromatography Systems By using liquid chromatography systems (e.g. FPLC, HPLC), a very similar, yet much faster process, is applied, but is performed in an automated manner. Figure 26.2 shows a chromatogram of a successful human IgG puri...
Protein A affinity chromatography has been widely used for both laboratory scale purification and commercial manufacturing of monoclonal antibodies and Fc-fusion proteins. Protein A purification is specific and efficient. However, there still remain several issues to be addressed, such as incomplete cleara...
Protein elution was carried out with buffers containing 200 mM imidazole and 500 mM imidazole. Proteins were further purified by size-exclusion chromatography, with a Superdex 200 10/300 Increase column, using an automated Äkta pure system in buffer containing 20 mM MOPS pH 7.8, 150 ...
